How Can I Achieve Dynamic Variable Creation in C# for Scenarios Like GridView Row Assignment?

Dynamic variables in C#create

C# adopt a strong type system that does not allow dynamic creation variables. However, there are some alternative methods to achieve similar functions.

Use the array

You can create a variable array, but this is not as flexible as other options.

Use the dictionary

In C#, a more effective method is to use the dictionary, which allows you to connect the dynamic key (in this example) with its corresponding value. Examples as follows: In this code,

allows us to dynamically create variable names with an integer value. We can use dynamic keys to access these variables.

Application scenario

<code class="language-csharp">using System.Collections.Generic;

Dictionary<string, int> names = new Dictionary<string, int>();

for (int i = 0; i < 10; i++)
{
    names.Add("variable" + i, i);
}

Console.WriteLine(names["variable5"]); // 输出 5</code>

Dictionary<string, int> In your specific scene, you need to assign dynamic variables to the line in GridView. You can use the dictionary as follows:

Create variable names by using dictionary dynamic dictionary, you can obtain the flexibility and ease of use in the scene. Please note that the use of access line indexes directly in the incident is a more direct and efficient method without creating an additional dictionary. The dictionary method is more useful when it is necessary to associate line indexes with other custom data.
